I'm trying to calculate this 'new' discovery of planet 9 the one that these peoples say is the mass of neptune or there abouts, and I used 600 Au, as the distance between them. ((since I want to know the gravity between them)) Is this equation correct?
1.989 x 10^30 * 1.024 x 10^26 = 5.5364225e+30 Or 5.536422 x 10^30 ((I think))
5.5364225e+30/ 600au (au is astromical unit maybe I should use miles?)
It spits out 9227370833333333333333333.3333333 when I put this in. So is this correct? I'm sorry I'm not good at math at all. I just want to prove the point that the mass of this object can't still be around the sun at how far out it is. So I want to check if this is valid. And if not, then please tell me how its not and How stupid I am and correct me with your superiority.
What is the 600 Au? Where did you get your information from. Pluto is ONLY 39.48 Au from the Sun. This supposed "new planet" is about 25 Au from Pluto. So, if that's true, then it makes it about 65 Au from the Sun. Also, it is NOT enough to know that it is the size of Neptune, because its gravity depends on its mass AND its radius.
((same person as poster))
I looked up a few artcicles some of them said that its 200au, others go out further? I'm not sure on this 'distance' thing,
AH! Here is the so called actual published article.

This is just one image from the article above that I was TRYING to make more simple for my stupid brain to work out.
There are a few more in the artcle. Some more simple. They really do say its about as big as Uranus which is why I used its mass for the thing I did. I would just put uranus up there in calulations and see of it can exist as far out as these two people say it can. I just don't think that an object that massive can exist beyone pluto since the suns gravity is pretty weak and a planet that massive just will shoot off.
I mean closer to the sun we get us, jupiter and such and that's good, but its still fairly far out, further then pluto and Eris by quite a bit.
They are trying to explain anonmolies in the kupiter belt, and Oort cloud aparently. Which can 'only be done with a massive planet' or some such. I don't really know, I just don't think that the sun can hold it down THAT far away. ((I do know the difference between the Kupiter belt and Oort cloud keep in mind. This is just what I gleen from the article))
